This article presents a numerical study on the non-similar model of mixed convective flow of nanofluid. The effects of various dimensionless numbers on flow properties are analyzed using graphical analysis. The results show the changes in flow profile, thermal profile, and concentration with respect to these dimensionless numbers.
This article presents the numerical scrutiny of the non-similar model of mixed convective flow of nanofluid initiated by an exponentially expanding sheet. Equations are modeled and transformed into non-dimensional partial differential system (PDE's) by defining dimensionless xi(x) as non-similarity variable, and eta (x ,y) as pseudo-similarity variable along with appropriate transformations. Graphical analysis for various dimensionless numbers such as thermophoresis (N-t) , ratio of mass and heat transfer Grashof numbers (N), Brownian motion (N-b) , buoyancy parameter (lambda) , Eckert number (Ec) and Lewis number (Le) is presented using local non-similarity (LNS) via finite difference based algorithm bvp4c. A raised flow profile wasobserved with increasing lambda and N. Boost in thermal profile was noticed for lager N-b . Increasing N and xi decreases the temperature profile. The concentration was a decreasing function of N-b , Le and N and increasing function of N-b .
